how to kill
Wen you are in 1v1 fight, stun the target and use Heartseeker Strike and if he survive kill him with spear shot.In team fight you will be focused so try to be behind ur friends but if someone comes to close, you stun him and kill him with ur team.If ur team is in team fight jump with ulty on the enemy team it will do big dmg and will help ur team to beat them.
Try it you will like it trust me.
